Ambiance & Radiance colors is a theme pack that provides Ambiance and Radiance themes in 9 different colors: blue, brown, graphite, green, orange (different than the one used by default in Ubuntu), pink, purple, red and yellow. The pack supports Unity as well as Xfce and LXDE/OpenBox (it doesn't work very well in GNOME Shell because Ubuntu's Ambiance doesn't either - they don't support client side decorations).
